Example
The QTimer::singleShot is used to call a slot/lambda asynchronously after n ms.
The basic syntax is :
QTimer::singleShot(myTime, myObject, SLOT(myMethodInMyObject()));
with myTime the time in ms, myObject the object which contain the method and myMethodInMyObject the slot to call
So for example if you want to have a timer who write a debug line "hello !" every 5 seconds:
.cpp
void MyObject::startHelloWave()
{
QTimer::singleShot(5 * 1000, this, SLOT(helloWave()));
}
void MyObject::helloWave()
{
qDebug() << "hello !";
QTimer::singleShot(5 * 1000, this, SLOT(helloWave()));
}
.hh
class MyObject : public QObject {
Q_OBJECT
...
void startHelloWave();
private slots:
void helloWave();
...
};
